style="text-indent:25px">【正盟環(huán)保】如何選擇助焊劑對于使用廠商來說，因為助焊劑的成份是沒有辦法做出測試的.如果要想了解助焊劑溶劑是否揮發(fā)，可以簡單的從比重上測量,如果比重增大很多，就可以斷定溶劑有所揮發(fā). 選擇助焊劑時，有以下幾點建議給使用廠商：一、聞氣味初步斷定是用何種溶劑如甲醇味道比較小但很嗆，異丙醇味道比較重一些，乙醇就有醇香味，雖然說供應(yīng)商也可能用混合溶劑，但要求供應(yīng)商提供成份報告，一般他們還是會提供的；但是，異丙醇的價格大概是甲醇的3-4倍，如果和供應(yīng)商壓價的厲害，可能這里面的東西就不好說了二、確定樣品這也是很多廠商選擇助焊劑的根本的方法，在確認(rèn)樣品時，應(yīng)要求供應(yīng)商提供相關(guān)參數(shù)報告，并與樣品對照，如樣品確認(rèn)OK，后續(xù)交貨時應(yīng)按原有參數(shù)對照，出現(xiàn)異常時應(yīng)檢查比重，酸度值等,助焊劑的發(fā)煙量也是很重要的一個指標(biāo)。三、看資質(zhì) 助焊劑市場是良莠不齊，選擇時對供應(yīng)商的資質(zhì)應(yīng)該進行確切了解，如有必要可以去廠商去看廠，如果是不正規(guī)的焊劑廠商，是很怕這一套的。深圳助焊劑原理杭州正盟環(huán)保工程有限公司有好的產(chǎn)品和專業(yè)的銷售和技術(shù)團隊。</p><div style="width:100%;text-align: center;"><img

②提高產(chǎn)品質(zhì)量：由于免清洗技術(shù)的實施，要求嚴(yán)格控制材料的質(zhì)量，如助焊劑的腐蝕性能（不允許含有鹵化物）、元器件和印制電路板的可焊性等；在裝聯(lián)過程中，需要采用一些先進的工藝手段，如噴霧法涂敷助焊劑、在惰性氣體保護下焊接等。實施免清洗工藝，可避免清洗應(yīng)力對焊接組件的損傷，因此免清洗對提高產(chǎn)品質(zhì)量是極為有利的。 ③有利于環(huán)境保護：采用免清洗技術(shù)后，可停止使用ODS物質(zhì)，也大幅度地減少了揮發(fā)性有機物（VOC）的使用，從而對保護臭氧層具有積極作用。</p><p
